Types of Power Wheelchairs
#1
What type of
DRIVE
is required?
(FWD, MWD, RWD)
Front-Wheel Drive Power Wheelchair
In a front-wheel drive power wheelchair, the drive wheels are in front of the client’s seated
position. The directional stability can become a challenge at high speeds due to the ‘fishtailing’ effect as there is not enough weight behind the centre of gravity to compensate for
the front loading. However, a front wheel drive power wheelchair performs well climbing
hills and offers great curb climbing ability as long as the footrests are set to properly clear
obstacles. We currently do not offer a wheelchair with this configuration.
Mid-Wheel Drive
In a mid-wheel drive power wheelchair, the drive wheels are directly under the client. The
position of the user does then coincide with the center of rotation of the chair, which is
the most intuitive configuration to drive. The chair moves according to the natural axis of
rotation of the body and there is much less need for anticipation when steering from one
direction to another. Due to this configuration, the turning radius of the chair is also smaller
than the other configurations (RWD or FWD), which makes it a significant advantage for
the predominantly indoor user. We have 3 types of mid-wheel drive chairs available that
are made in Canada: the Quickie X2, Xperience, and Xcel.
Rear-Wheel Drive Power Wheelchair
In a rear-wheel drive power wheelchair, the drive wheels are behind the client’s seated
position. Due to this configuration, rear-wheel drive chairs typically have a larger turning
radius which is unfavourable for indoor use, but offers the best directional stability at high
speeds. A RWD chair is usually preferred by predominantly outdoor users. We offer the
Quickie Xplore in a rear-wheel drive configuration.
Power Assist Wheels
This refers to a hybrid configuration of a manual and power wheelchair. The wheels are
mounted onto a manual frame and have a battery-powered motor that assists in moving
the chair as the client pushes. This is an ideal option for a client who requires additional
assistance to propel a manual chair over steep obstacles or grades. Power assist wheels
should not be prescribed in lieu of a power chair. Please visit our website for more
information on our line of power assist wheels: Quickie Xtender at
www.SunriseMedical.ca.
SUNRISE SUGGESTION
Center of Rotation of the chair
Arc described by the head
as the chair rotates
Turning Radius of the chair
Consider the environment and the activities that the client will engage in when using a
powered chair. Is the terrain rough or a smooth surface? Will they use the chair at home
and at work? Do they live in the country or in the city? Generally, people who have a small
turning radius in a home setting will require a mid-wheel drive chair. Outdoor users will
benefit from a rear-wheel drive for greater stability.
If you are unsure about which type of power chair to suggest for your client, you can
always ask for a trial of different types.

Selecting Electronics
First of all, you need to know the difference between
Expandable vs. Non-expandable electronics...
#2
What type of
ELECTRONICS
are required?
Expandable vs. Non-expandable electronics
Refers to the degree to which the electronics selected for a wheelchair offer different
power options. This is an important consideration for the therapist, as a wheelchair with
expandable electronics can offer power features such as tilt, recline, elevating legrests,
and elevating seat functions. It is also important to note that expandable electronics
includes the option of prescribing specialty controls, such as a head array and buddy
button switches. It is also appropriate for clients with a progressive condition, such as ALS
or MS, since it will allow the system to be expanded to accommodate the changing drive
control needs of those client populations.
1. P&G VR2 70 AMP control (Non-expandable)
When selecting the VR2
70 AMP electronics, your
client will need basic power
only, with a functional
status that is expected to
remain stable over time.
Consists of 1 profile with 5 speed increments or up to 5 profiles with 1 programmed
speed. This will allow you to select various types of drives for your client (example: indoor,
outdoor, shopping, etc).
FOR EXAMPLE:
Profile 0: 5 Speed Increments 20/40/60/80/100% speed
Profile 1: Inside (1 speed only)
Profile 2: Outside (1 speed only)
Profile 3: Rough Terrain (1 speed only)
Profile 4: Going into a Van (1 speed only)
Profile 5: Going up a Ramp (1 speed only)
This type of controller is used with a joystick only so it does not offer the client different
types of operating options.
When selecting the VR2
90 AMP electronics, your
client can be prescribed
1 power option; however,
functional status is
expected to remain stable
over time.
This can be selected on our Quickie X2 model only
2. P&G VR2 90 AMP control (Non-expandable)
As above, however, it can provide activation of 1 power option through the joystick
(i.e. Attendant control).
This can be used on any of our Canadian-Made power wheelchairs
The controller is to be used with a joystick only

Selecting Electronics (Continued)
3. P&G R-Net Entry Level (EL) – (Expandable)
90 AMP controller
Fully programmable with up to 8 profiles. Sold with 4 profiles turned on
Seating Options can be
prescribed with the R-Net
Expandable electronics.
Think of your client who
requires seating options
such as tilt/recline/power
elevating legrests
Bluetooth compatible
Considered ‘mid range’ with respect to expandable electronics
omes with an LED joystick (which has an icon of the chair, so the user knows which
C
function they are using visually)
Multiple Seating Systems can be prescribed (tilt/recline/power elevating legrests)
4. P&G R-Net 120 – (Expandable)
As above, however, fully programmable with 8 profiles
120 AMP controller
Is considered ‘higher end’ with respect to expandable electronics
Compatible with existing specialty controls or newly prescribed specialty controls
Compatible with Infra-Red (IR) Functions
The seat options can be operated through the joystick or other specialty controls
Intelligent Seating Module
included. Think of your
client who requires
multiple power functions.
This system is well suited
to be compatible with
Environmental Control Units
as well!!
Speed adjustments can be accomplished through push buttons or a speed pot
Compatible with home automation and environmental control units
MNI board included (portal which allows a user to communicate with their environment
O
i.e. operate TV, lights, garage door, etc.)
Intelli-Drive option available
Recommended for predominantly outdoor users or those who require high torque at low speeds
Also recommended for bariatric clients who require power options.
NOTE: Intelli-Drive
Intelli-Drive is one of the unique characteristics offered on the Canadian-Made power
wheelchairs with Sunrise Medical. In simple terms, it tracks straight while allowing users
to conquer slopes, thresholds and obstacles. This feature is compatible with R-Net
expandable electronics, which is described in a separate section of this manual.

Operating the Wheelchair
Joystick Drive (Proportional)
#3
This is the most common method of driving the chair. A joystick, looking similar to one
on a video game, is moved by the user’s hand to operate the chair. The joystick can be
mounted on either side of the chair. In addition, we offer height adjustment as well as
angle adjustment to permit the joystick to swing away and down and angle (permitting
user to have better access to tables)
How will my
client OPERATE
the wheelchair?
On any of our joysticks, you can select from a stick handle, ball handle, foam ball handle,
or T-Handle to operate the chair.
Operating the Chair without a Joystick
– Specialty Controls
Proportional Head Control
Combo Sip &Puff
Head Array
Chin/Lip Control
This refers to a method of driving the chair using a smaller joystick located next to the
chin/lips. Movements of the chin/lips operate the chair. This is used for someone who has
good head control, but limited arm and hand function.
Head Controls
This refers to another method of controlling the chair and it is used when someone does
not have good hand or arm control, but good head control. These can be proportional or
non-proportional.
Head Array with Sip and Puff Controls
This device utilizes the sensor switches for left and right directional movement and uses
the Sip and Puff for Forward and Reverse operation of the chair. The Centre Pad is nonoperational.
Sip and Puff Control
This refers to another method for driving the chair and is typically used for someone who
is unable to operate the chair with head, arm, or hand controls. The person will use hard or
soft sips or puffs on the straw to operate the chair.
MicroPilot
Proportional
This is a unit that is suitable for chin, finger, thumb, or other extremity applications. An
example is the Switch-It MicroPilot which is adjustable from 10-50 grams of force. There
are 3 different types of mount configuration – chin, finger, and thumb control.
REMEMBER, you will want to go with the expandable R-Net 120 AMP electronics in order
for your client to utilize specialty controls.
Scanning
Can be used in combination with the above, or with any of our switches, and gives the
user a screen that constantly rotates the various functions available. The user may stop
the scanning by activating a control in order to utilize the function being offered.

Switches
Egg Switches
Buddy Button
Mini 1 Button
MicroLite Button
By pressing a switch, the chair will activate from anywhere the switch is mounted. There
are several different types of switches available on the market today and some examples
are listed below. The switches are easily cleaned, come in a variety of different colours,
and some can provide both tactile and auditory feedback. In addition, the switches can be
ordered with varying levels of force required to activate the switch; so someone with a very
light touch will still be able to utilize these switches.
•
Buddy Button Switches – Range from 2 ½ inch surfaces to 4 ½ inch surfaces and
require a slight touch to activate. They come in different colours and provide tactile
and auditory feedback.
•
Egg Switch – Is a switch that activates from anywhere on its surface. It is easily
cleaned and it comes in a variety of colours. Tactile and auditory feedback.
•
Fibre Optic Switch – The fibre optic switch can be programmed for either NO or NC
operation. In the normally open (NO) mode, switch activation occurs when an object
is detected in the adjusted range. In the normally closed (NC) mode, switch activation
occurs when an object is no longer detected in the adjusted range.
•
Flex Switch – Activated by bending the top of a rubber tip in any direction. Attached
tubing can be bent to aid in positioning. Tactile and auditory feedback.
•
Grasp Switch – The tub shaped switch is activated by a squeeze or a pinch. The user
must be able to release the grip in approximately 2 seconds in order to prevent switch
lagging.
•
MicroLite Switch – Activated by pressing down on the top of the switch with a
feather-light touch. Tactile and auditory feedback.
•
Mini-cup switch – Is easily activated by finger or chin and comes with 5 different
coloured stickers. Tactile and auditory feedback.
•
Pillow Switch – A smooth and soft foam surface makes this suitable for head or
cheek activation. Tactile feedback.
•
Plate Switch – A very thin membrane switch activated with a light touch on a
coloured circle. The surface is sealed to prevent moisture damage. No tactile or
auditory feedback.
•
Ribbon Switch (also known as Leaf Switch) – Activated by bending a ribbon in
either direction. It is soft to the touch and moisture resistant. Tactile feedback.

Programming the Electronics
How can I help
my client use
powered mobility
SAFELY?
Any of these features are easily set up through the use of one of our programmers.
Our sales team in the field can walk the vendor through this process at any time – just let us know.
Please be advised that the options shown below are but a selection of what is
available for the client when using these electronics.
R-NET
VR2
POSSIBLE OPTIONS
√
√
Active/Joystick Throw – This allows the control system to be programmed so that full speed can
be reached with a reduced joystick movement (throw). This is particularly useful for wheelchair users
with limited hand or arm movement who will not be required to move the joystick as far in order to
achieve the desired result.
√
√
Actuator Parameters – Allows the adjustment of parameters in percentiles. For example, forward
speed can be set to 60% of the total allowable speed for a client’s safety.
√
Actuator Selection – Sets whether the joystick can be used to select between actuators. Each
actuator is set between 1 or 2. For example, an actuator could be a tilt function; therefore, the
actuator will allow: (1) tilt up or (2) tilt down, operated through the joystick when in the seating
module. A second actuator could be elevating legrests, a third could be recline, etc.
√
Actuator End Stop Beep – This allows the use of an audible beep to tell the user when the actuator
is stalled at its end stop. For example, this will provide auditory feedback to allow the user to know
that they have reached the maximum allowable movement - i.e. maximum tilt reached, and as such,
should prevent the client from continuing to send power through the joystick for that particular
actuator function.
√
√
Deadband – There is a neutral/dead area or band in which there can be movement of the joystick
before it engages a function. This parameter allows the user to open up that area so that it is larger
than the normal area. This is useful for the client if they have a tremor or if the joystick handle has
been exchanged for something heavier than the standard and more neutral area is required.
√
√
√
Invert Joystick (VR2)/Access Selection (R-NET) – This parameter inverts the direction of travel
when moving the joystick. For example, pushing the joystick Forward will result in Reverse drive.
√
Lock Function Enable – This allows the chair to be locked from driving. Our default setting is for
this function to be enabled and is activated by a sequence of movements. For example, a movement
of forward and then reverse, after pushing the power button on, will result in a lock-out (the
sequence of movements to lock-out the chair can be changed, or turned off altogether). This can be
beneficial for clients who would like to ensure that other members of the home will not misuse their
equipment when it is not in use.
√
Power-Up Mode – This allows the user to decide what mode they want to be in when the power
is turned on instead of having it default to the last one which had been used before the power was
turned off. Usually the first function they would choose to activate (i.e. drive, seating, ECU, etc.)
would make sense to be the one for Power-Up Mode.

Table continued...
R-NET
VR2
POSSIBLE OPTIONS
√
Profiles – A drive profile is a collection of functional parameters including acceleration, deceleration,
turn acceleration, turn deceleration, forward speed, reverse speed, turn speed, power and torque
which can be set for the individual user. The number of profiles will vary depending on whether
standard or expandable electronics are prescribed. The parameters allow you to program minimums
and maximums according to the needs of the client. For example, indoor acceleration and
deceleration can be quite different from outdoor acceleration and deceleration.
√
Read System Log – The control systems have a diagnostics log facility which stores the number
of occurrences of the last eight trip codes. A trip code is an error code. R-Net always stores the
last code which occurred as the first to be looked at whereas VR2 does not. These codes will allow
your dealer the opportunity to further investigate an error and get to the root cause of a malfunction
(should one occur) to resolve the issue quickly.
√
√
Read Timer – The controller has a timer which records how long the wheelchair is in use. The
timer runs whenever the joystick is moved away from the center position, and stops when the
joystick is returned. The timer records the number of hours the wheelchair has been in use. This
could be helpful for therapists who need additional insight as to how often the chair is in use, or for
determining how far a client can travel before the battery levels start to deplete.
√
√
Reverse Driving Alarm – Sets whether the control system gives an audible warning while driving in
reverse.
√
Sleep Timer – A length of time can be set, such that if the control system accepts no valid input
for that period of time, it will power down safely. This is useful when the client has a tendency to fall
asleep or is on heavy medication. The default setting is 0 and does not engage the timer; however,
the range is 1 - 30 minutes, and can be set according to the needs of the individual.
√
√
√
Sounder Volume – This allows setting the volume for sound when commands are used to change
modes or profiles through the joystick. The default is 10 (maximum) but choices are available all the
way to a 0 setting which provides silent operation. This can be set to the individual user’s preference.
√
√
Speed Adjustment While Driving – This parameter sets whether the control system’s speed/profile
buttons are active while the wheelchair is driving. This adjustment is particularly useful for users who
may accidentally operate these buttons while using the joystick. The factory default setting is No.
√
Steer Correct – This factor compensates for any mismatching of motors to ensure that the
wheelchair drives directly forward when the control system’s joystick is being pushed directly
forward. This is helpful for wheelchair users who over time can experience an imbalance of the motor
values due to active wear and tear.
√
√
Torque – This parameter boosts the current to the motors at low speed settings. If the motor is
stalled, for example when the wheelchair is stuck against an obstacle, such as a door threshold;
then this will be automatically detected and the current to the motors will be increased, allowing the
obstacle to be overcome.
√
√
Tremor Damping – This parameter allows the effects of hand tremor to be reduced. If the user has
a condition that results in hand tremor, then increasing the value of Tremor Damping will reduce the
effect of the tremor, making the wheelchair more controllable.

Additional Definitions and Terms
Environmental Control Systems and Bluetooth Technologies
Refers to a system permitting remote control of electronic devices in the immediate environment. For example, a person
can independently turn on and off lights, a radio, and a television, answer or initiate phone calls and unlock a door.
Advanced technology now allows some wheelchairs to interface with environmental control systems depending on the
electronics prescribed.
Group 22NF vs. Group 24 Batteries
Refers to the amount of AMP Hours (ampere-hour, Ah) that the battery contains. Group 22NF batteries have up to 55 AMP
hours, while the Group 24 batteries have up to 75 AMP hours. So, 55 AMPs refers to a battery’s size and capacity. As an
example, when someone is driving on level ground, approximately 10 AMPs of current is being applied.
The high quality German made motors of the X-Series wheelchairs have one of the lowest power consumption rates in the
industry which provides a maximized range to the user. This range can be up to 49.2 km with Group 22NF batteries* and
up to 68.5 km with Group 24 batteries*. (*According to ANSI-RESNA test protocol. Tests performed by an independent laboratory.)
2 Pole vs. 4 Pole Motors
This refers to whether a motor uses 2 brushes or 4 brushes to allow the current to flow. In a 2 pole motor system, the
brushes are dependent on one another for the system to operate. In a 4 pole motor system, if 1 brush fails, the remaining
3 brushes will continue to operate the system; however, there will be a noticeable difference in the drive, indicating that
something has gone wrong.
The choice between a 2 pole and 4 pole motor should be made based on the environment, expected usage and weight
of the individual. 2 pole motors are usually selected for ‘light-duty applications’ for an average weight user and riding
predominantly on indoor or ‘regular’ surfaces. The 4 pole motors will perform better for predominantly outdoor users,
average to heavier weight with a high level of activity, or those who need precise control at low speeds (specialty control
or apprehensive users).
Proportional vs. Non-Proportional Electronics
Proportional electronics refer to how the electronics are operated. For example, when you drive a car, the gas pedal would
be considered proportional, as you increase pressure, the car moves faster and you have to keep holding the gas pedal
down. A joystick is considered proportional. There are many options today, depending on client needs, but to keep things
simple, think of non-proportional electronics as those in which a user can touch the control once, the system will then be
activated like a light switch being turned on or off. Once you move away from the switch the activity stops.
Torque vs. Power
Power refers to the maximum output from the controller. Power is rated in AMPS; therefore, a PM120 is equivalent to 120
AMPS. Torque refers to the ‘start-up’ power. It is a parameter that boosts the current to motors at low speed settings and
is useful for users to overcome obstacles such as ramps and grade variances.

A NOTE ABOUT PRESCRIBING Power wheelchairs
FOR THE PEDIATRIC POPULATION
Powered mobility can greatly enhance the lives of toddlers and
children!! Determining when a child is ready for powered mobility
is a process that involves your assessment of their cognitive and
sensorimotor abilities and then introducing the child to a powered
mobility device. It is important to observe how they explore the
device. A child should become interested in the device with their
own drive and curiosity, otherwise, they are likely not ready to
pursue this goal. Powered mobility can lead to a better integration
with their environment, resulting in a more active lifestyle. The
fear that the child could become lazy, or lose strength, can be
compensated for by an appropriately prescribed exercise routine.
We have seen children as young as 12 months begin to use
powered mobility! This is interesting since the average child usually
begins to walk at 12 months of age.
We believe that powered mobility can allow children to reach
developmental milestones at the same ages as their able-bodied
peers. Of course safety is of the utmost importance! When
toddlers and children become interested in powered mobility, we
recommend that the therapist or caregiver use a dual attendant
mode in order to toggle between the attendant or child controlling
the chair. In addition, programming the chair to match the
developmental milestones of the user is quick and easy and we
would be happy to consult with you in order to achieve this goal!
If you would like additional information on the prescription of powered mobility for toddlers and children,
RESNA has published a paper entitled ‘RESNA Position on the Application of Power Wheelchairs for
Pediatric Users’ (2009) and is available to download at no cost from their website at:

This is an excellent read!!
